To all rv/2.0m it may concern:

Be it known that I, (inoncu G. (lumen, a citizen of the United hilatee,res-dding at Giul- Yeston, in the county of Galveston and State of'lexas, have invented a new and useful luternaMloiulnition Engine, ofwhich the following, a specification.

The present invention relates to improveincurs in internal combustionengines, one ohject of the invention, being the provision of an engine,the cyliiuflcr oi. which is pro- 'vided with a semi-spherical upper end,for the rotatable reception of a similar shaped power cylinder carryingshell, the upper end of said. shell being, provided with a single portfor eontrollimn the intake and exhaust ports of the engine, said shelltherefore con-- atituting: a rotary valve and combined oomhuetion' andpower chamber, of the engine.

A further object of the invention, is the provision of an internalcombustion engine, the outer casing of the cylinder of which is providedwith an intake and exheusit port. ihcre being disposed within the same,to form a lining therefor a rotatable shell, the upper end of whichconstitutes the explosion chamher, and is provided with a single portfor controlling the intake and exhaust ports of the engine during therotation of the" shell, there l'flfllhflf provided moans disposedexteriorlv of and connected to the upper end of the shell for holding:the same properly positioned relatively to the easing. and so as topermit the necessary longitudinal and lateral movements of the ehcll.due to the expansion and contraction oi the metals, wehr ot' the saidparts. and vihra'tion of the Faaid cylinder casting, and sheli inaction.

With the i'm'e roing'and other objects in view which will appear as thedescription proceeds, the invention resides in the combinationandarrangement of parts and in the details oi con tructfion hereinafterdescribed. and claimed. it being understood that I changes in theprecise embodiment of the in valve. Figi. 2-3 a plain view of thecomhined shell and rotary valve with the port thereof in elevation.

Each casing is prodided with the intalco cl'iamher l0 and thelljtillfl-E port 10, an intake llitlltlifiltl 11 being; led to thechmnhcr 10 in any desired manner. At a properly ascertained oppositepoint of the c vlinder 5, apprrmimntely 200 to 225 degrees distant fromthe intake port 10, is provided the exhaust cl'nnnhcr '12 having theexhaust port 12 which has leading: therefrom, the exhaust manifold 13.

The inner upper end ol the casing: 2, as clearly shown in Figs. 1 and Q,is formed FIKIT)lF plltl'ifffll. as at M and is cut away as at, 15 agreater part of the length of the 1011- griludiual wails thereof, sothat the semi-- spherical end to oi the rotary shell and valve '17 mayhe propcrl floated within the casino S from below so that the lower ring'lFw will abut". the lower inner wall of the one" inc 5 while thesemi-spherical end 16 Will engage the wall at 14, the intermediateporlog positioned to mesh. will or shell 1? and ill a point to best irealizes the filClZlOIl iii'in ilis relation of lhe 511 ll.
